\ FLASK Filed April 9, 1931 Patented Feb. 23, 1932 STATES EDWARD MOTLEY GUILD, 0F BROOKLINE, MASSACHUSETTS FLASK Application filed April 9,

This invention relates to flasks. It is the chief object of the invention to improve the construction of flasks with a view to making them easier to fill, more convenient to drink from, and to combine, in effect, a cup and flask.

The nature of the invention will be readily understood from the following description when read in connection with the accompanying drawings, and the novel features will be particularly pointed out in the appended claims.

In the drawings,

Figure 1 is a perspective view of a flask constructed in accordance with this invention;

Fig. 2 is a view, partly in side elevation and partly in vertical section, of the upper end of the flask; and

Fig. 3 is a plan view of the flask.

The flask shown in the drawings comprises a main body 2 which is relatively flat and preferably curved transversely so that it may better fit in a pocket. Formed in the upper end of the flask is a cavity or cup 3 which is separated from the chamber in the main body of the flask by a partition 4:, this partition forming the bottom and one end of the cup. The opposite end and the sides of the cup are bounded by the walls of the flasl The cup may be closed by a cover 5 which is hinged to the flask at 11. An opening 6 for filling the flask and discharging the liquid contained therein is made through the partition 4 which forms the top of the main chamher in the flask. Preferably this opening is tapered, as shown in Fig. 2, and it is made of substantial length, the walls of the partition 4: being thickened for this purpose.

An important feature of this invention resides in a device which serves both to close this opening tightly and also to hold the cover 5 in its closed position. As shown, this device includes a plug 7 made of cork, or other yielding material, and tapered to fit tightly in the tapered aperture 6. This plug is connected with and carried by a knob'which includes a head 8 and a shank 9, the shank i extending loosely through a hole formed in 50 the cover 5 so that the knob can rotate freely 1931.

relatively to the cover. The knob also carries an externally screw threaded closure or cap 12 which is adapted to be screwed into the 9of the knob extends, and the two shanks are secured together bya pin 13. In order to enable the on the cover 5, the plug is arranged to slide relatively to the knob and the cap 12, and a spring 14 is interposed between the knob and plug and tends to force these two members apart. 7 The plug is held to the knob, however, by a screw 15"which passes through a sleeve 16, one end of this sleeve abutting against the'head of the screw while its other 1;

end bears against the lower end of the shank 9.

In using the flask the knob may be, rotated tounscrew the cap 12, after which the cover 5 may shown in Fig. from this flask just as he would from a cup.

'Inclosing the flask the cover is swung into position and also to maintain the head 8 in its cover clamping position. Preferably the cover, when closed, forms substantiallya continuation of the side walls and top of the main body of the flask so that the entire device presents a smooth outer surface interrupted only by the head 8 of the knob and by a partof the hinge 11. I i

The invention thus provides a flask which is exceptionally convenient to use, presents a neat and attractive appearance, and which can be closed tightly oropened easily when internally threaded upper portion of the op en; mg 6. As shown, this cap is provided with a'hollow tubular shank into which the shank plug or stopper 7 to find itsseat in the tapered hole 6, while still allowing the head 8 of the knob to be forced down tightly be swung intoan open position, as;-

l. The user can then drink rotating the knob, the cap 12 is threaded into the upper end tapered hole 6, the 7,

accomplished indedesired. An important advantage of this flask is that it is much easier to flll than the ordinary flask due to the fact that no funnel is required in filling.

Having thus described my invention, what I desire to claim as new is:

1. A flask having a cup in one end thereof, said cup being bounded at its sides and one end by the walls of said flask, the bottom of said cup forming a part of the top of the main chamber in the flask and having, a filling opening therethrough, a cover for said cup, and a device for closing said opening and also holding said cover in its closed position.

2. A flask having a cup in one end thereof, said cup being bounded at its sides and one end by the walls of said flask, the bottomof said cup forming a part of the'top of the main chamber in the flask and having a tapered filling opening therethrough, acover for said cup, a tapered plug for closing said opening, and a support for said plug carried by said cover and adapted to hold the cover inits closed position.

3. A flask having'a cup in one end thereof, said cup being bounded at its sides and one end by the walls of said flask, the bottom of said cup forming a part of the top of the main chamber in the flask andhaving a filling opening therethrough, a hinged cover for said cup, a knob rotatably carried by said cover and having a head to-bear on the cover and a shank extending through the cover, a closure for said opening carried by said knob, and means on the flask with which a part carried by the knob is adapted to be releasably engaged to hold the closure in its operative'position and to cause the knob to hold the cover closed.

4. A flask having a cup in one end thereof,

said cup being bounded at its sides and one I end by the walls of said flask, the bottom of said cup forming a part of the top of the main chamber in the flask and having a tapered filling opening therethrough, a cover for said cup,'a tapered plug for closing said opening, a part of said opening being internally screw threaded, a screw threaded device'for engaging the internally threaded portion of said opening, a spring interposed between said device and said plug, and a knob rotatably mounted in said cover and carrying said device.

5. A flask having a tapered filling opening, a tapered plug adapted to fit in said opening, a support for said plug, and a spring for pressing said plug away from said support, said support and flask having cooperating and relatively rotatable parts for releasably securing the support to the flask independently of said plug.

6. A flask having a tapered filling opening, a tapered plug adapted to fit in said opening, the upper part of said opening beinginternally screw threaded, a cap adapted P EDWARD MOTLEY GUILD.
